Primer is meant to seal unfinished as well as finished surfaces. It helps the top coat of paint to adhere to the wall surface so that your finish looks good and lasts a long time. One of your best resources would be the instructions that are given on the container of your paints and primers. This will help ensure that you have adequate amounts for the job as well as offer guidelines on the right kind of cleaner you will need for your brushes or rollers. Read the instructions carefully as they also guide you on the drying time necessary between coats, whether you will require a primer or possibly an undercoat and if this is the case, what kind to buy.
Keep in mind that there are different types of primers locally available such as wood primer, stabilising primers and metal primers so choose a reputed brand according to your needs.

You need to know the type of paint that you intend to use over the primer, or the type of material that the primer is meant to seal before you paint it.

For example, an unfinished drywall surface can be primed with an acrylic primer and overcoated with an acrylic paint or an oil-based paint. But, if you prime it with an oil-based primer, you can only cover it with an oil-based paint. Similarly with paint. Oil and acrylics can cover acrylic paint. But only oil can cover oil. Never try to cover anoil-based anything with an acrylic paint. You will peel it off like Elmers glue on your hand! (Elmer's glue is water-based and will not seal against the oils on your skin).

Talk to your paint specialist salespeople. They are trained in those things.
